But across social media, the real-time reaction was significantly less enthused. The speech further illuminated growing divides in the Republican party, and brought frustrations with Trump's inconsistent immigration message to the forefront.

Some of Trump's most vocal allies, including conservative author Ann Coulter and former Arizona Gov. Jan Brewer, made their enthusiasm clear:

I hear Churchill had a nice turn of phrase, but Trump's immigration speech is the most magnificent speech ever given.

But other Trump allies, in Texas and elsewhere, seemed prepared to jump ship. Several prominent Latino leaders went online to express their frustrations with the Phoenix address, in which Trump reiterated his commitment to creating a "special deportation force" and building an "impenetrable, physical, tall, powerful, beautiful southern border wall" between the United States and Mexico.

Rick Figueroa, a finance executive from Brenham who serves on Trump's National Hispanic Advisory Council, called the speech disappointing and "a moral mistake." Figueroa, who introduced Trump at an Austin rally in August, included a link to a statement that has since been deleted from his website.

While some wavering Trump allies expressed their disappointment, other Republicans, many of whom have been long-time critics of Trump's platform, took the chance to further lambaste Trump for the internal ambiguities of his immigration policy. Jason Johnson, who served as Sen. Ted Cruz's presidential campaign strategist, said Trump lacked a coherent philosophy.

Let's give credit where credit is due. #TrumpAZ speech provided what all sides want to see. Perfect summary of his entire campaign.

Texas GOP consultant Matt Mackowiak and state Sen. Konni Burton, R-Colleyville, also expressed their disdain for the event. Burton noted that Rudy Giuliani and Sen. Jeff Sessions, who introduced Trump in Phoenix, wore the same hat — which read "Make Mexico Great Again Also."

This speech is totally unserious. Amateurish. Conway and Kushner must be embarrassed.
